L31 Elevator Parameter (Speed)
L31 specifies the elevator speed (mm/s) relative to the inverter's rated speed (F03).
The elevator speed (L31) can be calculated with the following equation.
L31 = Maximum speed (r/min) / Detected speed (r/min)
×
Elevator rated speed (mm/s)
(Example) If the elevator rated speed is 750 mm/s, the detected speed is 1350 r/min, and the
maximum speed is 1800 r/min:
L31 = 1800/1350 x 750 = 1000 (mm/s)
- Data setting range: 1 to 4000 (mm/s)
Changing the elevator parameter (L31) requires modifying the data of other function
codes. Refer to section 2.2.
L32 Elevator Parameter (Over speed protection level)
L32 specifies over speed protection level. If the speed of motor exceeds the over speed protection
level for a duration longer than the time set in L33, inverter will stop. When there is no L32,
protection level is constant 120%.
- Data setting range: 50 to 120 (%) (100%: setting value of max speed)
L33 Elevator Parameter (Over speed timer)
Over speed timer (L33) starts when the detection speed exceeds over speed level (L32). After the
timer ends, the inverter stops. When the detection speed decreases less than over speed level while
the timer works, the timer is reset and the inverter doesn’t stop.
- Data setting range: 0.000 to 0.500(s)
